That would make sense. Here concrete is expensive, so maybe that is why wood frame is often used. Cheaper to build. I would certainly feel a lot safer in a concrete home with a concrete roof during hurricane season. Much lower maintenance on a concrete home as well. Interesting how the USA home is typically built very cheap and fragile especially with all the natural disasters we get here. Your homes sound so much stronger and cheaper to care for after the initial cost to build.
Jonna - Thanks for answering my questions. I often wondered about your concrete roof house, too. Now I know. Much smarter way to build a house, in my humble opinion!
